4 Way Switch Circuits |

The most common use of 4 way switch circuits is to control one or more lighting fixtures from 3 or more locations. There really is no limit to how many switches that can be used, however on this site I have created wiring scenarios for 3 switches, if more is desired then read the article at the link bellow in regards to adding additional 4 way switches. Three way switches are also required at the beginning and end of the circuit, with 4 way switches between these.
There are a variety of different ways to wire a 4 way switch circuit, factors that can influence your selection can include...
personal preference
where the existing source of power is located
ease of routing new wire cables
number of wire cables required for a particular wiring selection which can also include box fill concerns
some wiring scenarios in instances where the new 2011 NEC 404.2(c) compliance is required could mean that at least in some parts of the switch wiring circuit, you will require a 4 wire (plus bare) cable. Although these types of cables are available they are not sold everywhere. If you have difficulty in obtaining a 4 wire (plus bare) cable or simply wish to avoid the need to get that, then choose a wiring selection that can comply with the new NEC rule (if compliance is required) and yet does does not require a 4 wire cable (plus bare), some wiring scenarios only require a 3 wire (plus bare) cable and will still comply with the new 2011 NEC 404.2(c) rule. 3 wire cables (which includes a bare wire) are sold in more places and therefore easier to get.
